If you are thinking about getting a projector instead of flat screen. Basically the way that the math works is that a 1000 lumen projector will give you 1000 lux against a square meter. Or to do another conversion 1 lux is 1 lumen per square cm. But there are lots of measures of what…

Well two things are true in life Hanlon’s Razor is not a bad one. Never attribute to malice that which is adequately exposing by stupidity. Hanlon’s Razor But absolute favorite rule for working in big companies is: Always postpone meetings with time wasting morons Dilbert channeled by Scott Adam’s And I could resist. Thanks Calvin…

Ok, hopefully you will never have to do this but we had a flat screen installed and during COVID we wanted to get a new one but didn’t want anyone at home so off to figure out to uninstall a flat screen The main trick is that behind the TV there is a latch and…

Ok starting with the pandemic and thanks to a great sale from Amazon I got a Kindle Paperwhite. Its the first kindle I’ve gotten since the very first original one with the keyboard. It was slow but it had a Sprint connection. In truth I never used it very much and I thought that the…

Well in the continuing quest to make this a HomeKit house, we spent some time looking for reliable garage openers that can be used with the Apple home application. There are quite a few smart garage door openers (and Wirecutter) but the best choice is not obvious. The Tailwind system is the most reliable because…

Well because of COVID we ended up getting four home filters for various folks and we even got an air quality monitor from kaiterra to monitor it. Net, net these things seem to work. When we didn’t have one on, our internal air quality rose to 84 on US AQI but putting one in dropped…

Well, now that the RainMachine seems to be working, the next project is at another house where there isn’t any sprinkler built in so how do you build something that can be HomeKit compatible so you can say things like turn the sprinkler on and and other general conditionals. There are quite a few automatic…

Ok, now that I’ve been on the bike for a year now doing 2,000 miles on an indoor trainer, its hard not to do some study and figure out thresholds for training. There is lactate threshold where your muscles start generating lactate and begin to burn out. The main idea is what % of VO2max…
